To ali/'whom tm/ay concern:l f

Be it known that-I, CHARLES A. HAMMEL, a citizenv of the'United States,residing at llos Angeles,'in the county of Los Angeles and Statev`o`f-Calitornia, have invented new and useful Improvements inHydrocarbon-Burners, of which the following is a specification.

The objects of my invention are to provide a hydrocarbon-burner composedof a number ol parts' easil f assembled and disassembled,-

in which -dup icate parts may be substituted for any of the partsinjured or destroyed by continuousf'use or otherwise; to provide aburner tl'ia-tl will practically atomize all the rcrude oil fed'thereto,and thereby Aeconomize in the use 'of oil and at the same time producethe'largest amount of heat therefrom..

Afurther object is to divide the steam into two jets, the one beingdirected at right angles against theother, both jets beinei regulated byone'supply-valve and the oil icing fed to vtheburner between the twojets of steam.y

I accomplish these objectsby means ofthe device described herein andshown in the accompanying drawings, in which- Figure `1 isa perspectiveview. of a hydrocarbon-burner embodying my invention, the oil andsteamsupply `pipes being broken away. AFig. 2' is a vertical section of myburner, taken on line 2 2 ot' Fig.. 5, looking in the directionindicated by the arrow-head thereon.; -Fig. 3 is a vert-icalvlongitudinal section taken. of the burner on the line indicated by line3 3 of Fig 6 looking in the direction. indicated by 'the arrow-headsthereon. Fig-4 is a -perspectiveview of the core or centralpart of .theburner removed from thefouter shell or casing. Fig. 5 isa transversesection of the device, taken on line 55 ol" F ig. 2, looking in thedirection in- Fig. 6 is a transverse section ofthe burner, taken on line6 6 of Fig; 2, looking. downwardly in the direction indicatedk by thearrow-heads marked thereon. Fig. 7 is a perspective view of a modifiedform of my burner adapted for use in a locomotive-engine. F ig. 8 is anelevation of the ymodified form with theface-plateremoved. Fig. 9 is avertical central section takenv on line 9 9 of Fig.

In the drawings, A represents the internal member or core, centrallydisposed in the outer casing or shell B.

arranged to register with a screw-threaded This central core isvprovided with a screw-threaded aperture A',

through which oil is fed to the burner, the l usual regulating-valvesfor regulating the quantity of oil and steam fed to the burner uot beingshown. This opening A forms an `)il-receiving chamber and terminates inthe mixing-chamber K, from which the vertical oil-supply channel D inturn communicates at. its lower e'nd with-the discharge-orifice E,through which the combined oil and steam is ejected into thecombustion-chamber.

. The bottom of the core is provided Awith the cavity A, which forms asteamreceiving and distributingchamber disposed immediately above thescrew-threaded opening B in thev shell, into which the steam-supply pipeF is screwed. Extending from this distributing-ehamber upwardly, one onea'ch side thereof and on each side of the mixing-chamber, are the twoupwardly-extending steamsupply ducts G, which communicate with 'thecavity H, which forms a steam-spreading chamber, in which the steam is sread out and passes downwardly throu h tiie narrow semicircular openingI, (see ig. 5,) formed at this point between the core and the casing B,into the mixing-chamber and commingles with the oil therein, from whichit asses downwardly on its way to the disc largeoriiice E.

By providing a downwardly-extending steam-duct from the spreadin-chamber above to the mixing-chamber be ow, which will impinge at rightangles upon the steamjet issuing fiom the bottom spreadingehamber towardthe discharge-orifice, thus one jet being directed against the other atright angles and the oil being fed between them will completely mix thesteam and oil and Form a combustible gas before leaving thedischarge-orifice of the burner.

'In'addition to this means of feeding steam to the burner I have rovideda narrow supplemental steam-disc arge orifice J, leading directlyvfromthe bottom of the steam-distributing chamberto thedischarge-orifice. This orifice J being narrow and somewhat .limited incapacity will supply only a part of the steamf'ed to the burner. Thesteam passj D on its way to the discharge-orifice. i They combinedell'ect of the feedingsteam through two orifices l argl J, acting on theoil, will cre- IOO IIO

tection to the bottom of the discharge-orifice f from the wearing actionof the foreign matter-such as boiler compound, sand, &c.-in the combinedsteam and oil as it comes downwardly from the mixing-chamber andprolongs thereby the lifetime as well as the efficiency of the burner.

The form of burner shown in Figs. l to 6,

inclusive, is adapted to throw outwardly a` fan-shaped blaze, while theform of burner shown in Figs. `'Z' to 8, inclusive, is adapted for usein a locomotive-boiler,wherein a longitudi- J nal flame is required andis especially adapted for use in locomotive-boil ers.

' Having described my invention, what l claim as new, and desire tosecure by Letters Patent, is-

1. An oil-burner provided with an outer shell having a centralcylindrical bore therein extending from the top thereof nearly to thebottom, said shell adapted to receive a cylindrical core, the said shellhaving a screwthreaded opening in the back thereof for the reception ofan oil-supply pipe, and a screwthreaded opening in-the bottom thereoffor the reception-of a steam-supply pipe, and a discharge-orificeextending outwardly from the bottom thereof, in combination with acylindrical core having a recess in the bottom thereof to form adistributing-chamber; a recess close to the top thereof to form aspreading-chamber; ducts leading from the distributing-chamber Vto thespreadin chamber, the said core being provided wit a central opening orrecess to 4form a mixing-chamber, a portion of the said core being cutaway be'- low the spreading-chamber and extending to the mixing-chamberto leave an opening between that portion of the core and the out'ershell when the core is in place in the shell for the passa e downwardlyo the steam from,

the sprea ing-chamber to t e mixing-chamber, the said core having alarger cut extending from the mixing-chamber to the discharge-'o eningto form a passage-wa y for the passage ownwardly of the combined oil andsteam from the mixing-chamber to the discharge-orifice.

oil-burner having a discharge-oriice; an oil-receiving chamber; aspreadingv chamber; a steam-receiving chamber; ducts leading from thesteam-receiving chamber to the spreading-chamber and an opening for thepassage of steam from the steam-spreading chamber to amixing-chan'il'ier; a mixingchamber communicating at one end with anoil-supply pipe and having at the other end thereof a downwardlyextended opening communicating with the discharge-orifice.

8. An oil-burner provided with a casing, a

cylindrical core havingrecesses formed there-` in for areceiving-chamber, a mixing-chamber and a spreading-chamber; thereceivingchamber communicating directly with the steam-supply and havingducts extending therefrom and communicating with the spreading-chamber;an orifice extending outwardly and communicating with thedischarge-orifice, an orifice extending downwardly from thespreading-chamber into the mixing-chamber and a larger orifice extendingdownwardly from the mixing-chamber to the discharge-orifice, the saidmixing-chamber being in communication with the oil-sup- 4. An oil-burnercomprising a cylindrical shell and a cylindrical core adapted to fitthereinto, the shell having a cylindrical bore therein extending fromthe top to near the bottom thereof, on the side thereof a screwthreadedopening for the reception of an oilpipe, on the bottom thereof ascrew-threaded opening for a steam-pipe, and a slit in the face thereofto form a discharge-orifice; the cylindrical core adapted to iit intothe bore of said shell and having in the bottom thereof a recess to forma receiving-chamber; ducts extending .from the top of said chamber'to aslit in the upperportion of the core to form a spreading-chamber; andhaving also a cutaway portion on the bottom thereof to form ,an opening.communicating with the discharge-orifice, the said receiving-chambercommunicating when in place in the shell with a steam-supply pipe; and acut-away portion of said core extending from the spreading-chamberdownwardly to a mixingchamber; the mixing-chamber centrally dis- -posedin saidcore and communicating with the oil-supply; and an enlargedcut-away IOO IIO

portion extending from the mixing-chamber to the bottom of the core toleave a passageway for the passage of combined steam and oil from themixing-chamber to the dischargeorifice.
